There was a problem hiding this comment.
We should check that the signal received from channel is sighup before stopping server in case we want to reuse signal handler

Why I did it
We want to reload the configuration of telemetry server if the certificate and key files are rotated. This PR is related to: [telemetry] Rotate streaming telemetry secrets. sonic-buildimage#9600.
How I did it
I created a signal hander which will stop current gRPC server and then create a new one with updated credentials if signal
SIGHUPwas received.How to verify it
I did this implementation and tested them on a virtual switch.
